UN climate chief urges 'bold' carbon-curbing steps

BERLIN - The UN climate chief on Sunday called on governments to take bold steps to tame carbon emissions after a landmark report said the worldwide aim to limit global warming was still attainable.

"The world can still combat climate change but only if nations raise their collective ambition to achieve a carbon-neutral world in the second half of the century," said Christiana Figueres, executive secretary of the UN Framework Convention on Climate Change (UNFCCC).

"We cannot play a waiting game where we bet on future technological miracles to emerge and save the day."

Figueres oversees UN negotiations towards a global pact on curbing climate-altering greenhouse-gas emissions that must be agreed in Paris late next year.
